Specification of Letters Patent.

Patented April 17, 1906.

Application tiled November 21,1905. Serial No. 288.361

Be it known that l, GUsTAF Anvm ANDER- sox, a citizen oi the United States, residing at W'aynesboro, in the county oi' Franklin 'and State of Pennsylvania, have invented certain new and useful .improvements in Gang- Plows g and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gang-plows which are operated byl traction-engines; and it consists principally of a novel and improved mechanism for operating the steering-wheel at the rear of the plow-frame 'from the steering-axle at the front end of the traction-engine, and it further consists in the means for connecting the plows together and to the plow-frame, as hereinafter Jfully described and claimed.

In the drawings, Figure l is a plan view in outline of a tractionengine and gang-plow constructed according`v to this invention. Fig. 2 is a plan view of the steering mechanism carried by the plow-frame and drawn to a larger scale. Fig. 3 is a side view of the steering mechanism. Fig.l 4 is a plan view showing the connection of one of the plowbeams with the plow-frame and showing also the gage-wheel. Fig. 5 is a side view of the same. Fig. 6 is a plan view showing the connection of two adjacent plow-beams with each other and the connection of one plowbeam with the lifting-beam. Fig. 7 is a side view of the same. F ig. S is a detail view of the eye S', drawn toalarger scale. Fig. 9 is a detail end view of the rock-shaft and its connections. ll) is a vertical section taken,l on the line a in Fig. 9 and showing also the radius-rod.

A is the boiler of a traction-engine oi' any approved construction.

A is the steering-axle, mounted on a pivot a at the front end of the traction-engine, and a represents the steering-wheels.

B represents the traction Wheels of the traction engine, and B.is the draft beam supported crosswise behind the tractionwheels by a frame b, which is secured to the boiler. y

C is the plow-frame provided at its iront l l l l end with arms c, which are pivoted to the draft-beam B.

C is the liiting-beam, which is operated by means of steam-cylinders c and intermediate connections of approved construction which are carried by the plow-frame. 4

D represents the plowbeams provided with ploWsAD. The plow-beams are supported from the lifting-beam C', as will hereinafter be more fully described. The plowframe is triangular, and at its rear end or apex it is provided with a steering-wheel E. This wheel is journaled in a suitable bracket having a vertical shaft E', which is journaled in a bearing c on the plow-frame. An armu e. is secured to the upper end of the shaft E for operating the steeringwheel- F is a vertical rock-shaft which is journaled in a vertical sleeve F. The sleeve F has a pivot or trunnionf, which projects laterally from its upper end portion, and this pivot is pivoted in a bearing f which is rigidly secured to the plow-frame. The rock-shaft is preferably arranged on the center line of the boiler and gang-plow in the middle part of the plow-frame.

G is a radius-rod provided at one end with a pin g, byv means of which it is pivoted to a lug on the lower part of the sleeve F', and g is a pin at the other end of the said rod, which pivots it to a lug on the beam B', which isse cured to the boiler.

H is Ila cross-bar which is secured to the lower end of the shaft F, and h represent two connections which extend b/etween the ends of the cross-bar H and the front axle A on opposite sides ol' its pivot. The connections 7i are preferably wire ropes, but any other torni or' connections, such as rods or chains, can be used, and they may be provided with turnbuckles and springs in the usual manner. TheseI flexible connections cause the rockshaft to follow the movements of the steering-axle as the said axle is moved to guide the engine around curves.

I is an arm secured to the upper end of the rock-shaft F.

is a connecting-rod, one end of which is pivoted to the arm l by a pini and the other end to the arm e by a pin i The arms l and e are set at certain angles and are made of a certain length, found by experiment, so that ICO when the two frames are moved and their connecting-rod are arranged in substantially the same .horizontal plane as the center of the pivot or trunnion f. In other words,l although the engine-frame and the plow-frame are pivoted together the radiusrod G always holds the flexible connections h at the same degree of tension or tautness, and' pivotally in f passing over rough ground the sleeve F and in the plates K K and k :connects the plow-beam rock-shaft F are rocked upon the pivot f. This rocking motion of the sleeve may vibrate the arm I slightly ina vertical direction, but

not sufficiently to cause a longitudinal movement of the rod I, which controls thesteeringwheel Each plow-beam D is connected with the diagonal member of the plow-frame by a Wooden pin connection, which breaks and releases the plow-beam when the plow strikes a rock o r stump. 1

J .isj'a bracket which is secured to the diagonal member of the plow-frame and provided at'its front end with angle-shapedlugs each ,having a vertically-arranged series of holes j.

K is ahorizontal guide-plate provided with lugs 7c at its rear end which are pivoted to the lugs by a pin V3-Which engages with the various o'lesy" and permits the distance of i guide-plate above the ground to be adjusted.

K is a slidable '.'lraw-plate which slides between the guide-plate K and a plate 7c, which is secured above the guide-plate by means of .bolts and distance-pieces L, sothat a broad guide-socket for the plate K is formed, which prevents the said plate from twisting or moving in any otherl direction than a longitudinal one.

L is the pin of hard wood or other suitable material, which isarranged vertically in holes and which normally to the plow-frame. The slidable plate K has lugs m at its rear end7 Which are pivoted by a pin M to brackets m on the front end of vthe plow-beam D. The dotted lines D2 in Fig. 2 indicate the center lines upon which the plow-beams D are arranged. The brackets m are provided with a plurality of holes for the pin M, so that the position of the plow-beam may be adjusted vertically.

N is a gage-wheel which supports the front end of the plow-beam. This wheel is jour- 'P or other equivalent naled on a pin a carried by a rectangular har 'n, which is slidable vertically in a socket N.

from catching against the lifting-beam when the wooden pin L breaks and the plow remains stationary. l/Vhen one or more of the wooden pins L break, the plows connected to such pins remain stationary. The engine continues its forward movement and drags along the frame C and the lifting-beam C,'together with the chains I. The chains P slide out of engagement with the fingers P, and the lifting-beamv C is thereby detached from the stationary plow-beams D and is carried off, the said plow-beams and plows being left behind. The plow-beams D are suspended from the lifting-beam C by means of chains flexible connections. P is a tooth pivoted to a bracket p by a pin 7 9. The tooth is arranged in a downwardly and forwardlyI inclined position, and g is a spring supported by the said bracket and pressing the front end portionof the tooth against the side ofthe plow-beam. The tooth I engages vwith one of the links of porting-chain, and when the wooden pin L breaks and the plow remains stationary the link draws off from the tooth and the plow is releasedfrom the lifting-beam. In order to hold the plows at the desired distances apart' and permit them to separate when the wooden pin L breaks, the adjacent plow-beams are coupled together.

R is a pin which projects laterally `from one plow-beam, and R is an l upwardly-projecting arm having an eye r at its lower end, which is pivoted on the pin R. :A collar r prevents the eye from sliding off the said pin. S is. a bracket which is secured to the neXt adjacent vplow-beam and Ywhich is provided with a bearing s at its upper end, which is arranged above the level of theplow-beam.

S is a loop-shaped guideor eye which is slidable longitudinally or lengthwise on the arm R. This guide is providedwith a pin s, which is journaled horizontally in the bearing s. .This arm land guide hold the plowbeams at a fixed distance apart, and when` the wooden pin of one plow-beam breaks the said arm and its guide turn on their pivots-and the arm is withdrawn longitudinally from the guide.

b When the steering mechanism of the gangthesup- IOO IIO

.the traction-engine and when the outfit travels .over rough and rolling ground. The roughness oi the ground, therefore, does not aiiect the steering connections h, which if the rockshaft were not 'pivoted would be torn asunder when the iront wheels of the traction-engine 'relatively higher and wouldbecome andthe steering-wheel of the plow-frame are than the traction-wheels too slack for steering purposes when the unevenness of the ground i raises the traction-wheels relatively above the aforesaid wheels.
